In the note, the cop killer claims those people closest to him would be surprised he was ‘suspected of committing such horrendous acts of violence’.

He continues that it was a ‘necessary evil’ that had to happen ‘in order to create substantial change within America’s police force and judicial system’.

Gavin claimed he had to inflict harm ‘upon bad cops as well as good cops in hopes that the good cops (which are the majority) will be able to stand together and enact justice and punishment against bad cops’.

Sounds delusional, right?

East Baton Rouge Parish District Attorney Hillar Moore III released an exhaustive report Friday about the details of Long’s suicide note.

The prosecutor showed videos, photos and graphics to reporters, depicting exactly how Long attacked police on July 17, 2016.

The report showed that Long had searched online for the home addresses of two white police officers who were involved in a fatal encounter with Alton Sterling, a black man who was killed outside a convenience store.

Investigators didn’t find any indication that Gavin Long ever acted on the information, and his research wasn’t the only evidence of his anger over the police treatment of African-Americans.

Moore said investigators didn’t find any evidence that Long had any support from anyone in Baton Rouge or attended any of the nightly protests here after Sterling was shot to death during a struggle with two officers on July 5.

‘We believe that he was ready to die this day,’ Moore said. ‘He believes that protests are worthless and that action needs to be taken, not protests.’

The prosecutor said that after Long killed three officers and wounded three others, he was shot dead by tactical officers who acted appropriately.

Long also had a printout from an Islamic holy book that was mostly in Arabic, and the report also found that he had been using methamphetamines and had alcohol in his system when he was killed that Sunday morning.

Serving in the Marines from 2005-2012, Gavin earned the ranking of Sergeant before he was honorably discharged.

The VA Medical Center in Kansas City, Missouri, diagnosed Long in November 2011 as suffering from an ‘adjustment disorder with depressed mood,’ but not PTSD; although Gavin claimed he had the disorder.

His mother stated right before Gavin’s shooting, any time a black man was killed by a cop – in what he considered an unlawful manner – her son would lose it and become furious.

In other words, he was a ticking time bomb and now 3 cops are dead because of him.
